Since 2000 Objects are scattered across 55 Tablespaces, but of Total
Data Size 8 GB only, I achieved the Data transfer from 1 Schema to
Another thru expdp - SCHEMAS=OWNER1 / impdp - REMAP_SCHEMA=OWNER1:OWNER2

NOTE - Database is a Testing Database. Hence Downtime is NOT an issue.

Qs Is Export , Import the the only way using 1 of the following?

exp - OWNER=OWNER1 / imp - FROMUSER=OWNER1, TOUSER=OWNER2 ,

expdp - SCHEMAS=OWNER1 / impdp - REMAP_SCHEMA=OWNER1:OWNER2

Cheers
